Beyond Decks: Complete Outdoor Living

Alliance Deck Builders of Sumter offers more than decks. We build full outdoor living areas including covered porches, outdoor kitchens, and sunrooms—each tailored to South Carolina’s weather and your lifestyle. Our designs are family-friendly, code-compliant, and made to handle everything from high humidity to weekend gatherings. Whether you want extra space to relax or an outdoor area to entertain, we’ll bring your vision to life.

Made for Heat, Humidity, and Year-Round Use

Smart Materials for the Sumter Climate

South Carolina heat and humidity can wear down poorly built decks—but not ours. We use moisture-resistant composite boards that hold up to summer sun, heavy rain, and daily wear. Prefer the natural look? Our pressure-treated pine and cedar builds are sealed and secured for long-term performance. We also install corrosion-resistant fasteners and design every deck with ventilation and drainage in mind. No warping, no mold—just outdoor spaces that last.
